I have a CRichEditCtrl in a CView class. I need to know when the control gets the focus and I don't know how to do it.
This is what I've done so far:
//On MyView.h
afx_msg void OnStupidCtrlGetFocus(NMHDR* pNMHDR, LRESULT* pResult);
//On MyView.cpp
ON_NOTIFY(NM_SETFOCUS, ID_STUPIDRICHEDITCTRL, OnStupidCtrlGetFocus)
void CMyView::OnStupidCtrlGetFocus(NMHDR* pNMHDR, LRESULT* pResult)
{
//Do some work
}
But it doesn't work !!! what am I doing wrong ????
Thanks in advance..

Hi all,
I create a button dynamically but as it is now, I create the button ID myself like this cause in this case I can't use the editor to create it:
#define ID_MY_BUTTON 33333
But how do I ensure a unique ID for this dynamically created button?

You can use _APS_NEXT_CONTROL_VALUE. Resource editor store here value which will be given to the next created control - so values above this not used.

i afraid it is good for first control but not for system dialog or any ole ctrls
there he must search all parent's sub-windows or similar (?)

Ok, so you mean that I can do like this:
m_pBtn->Create(_T("Button"), WS_CHILD | WS_VISIBLE | BS_PUSHBUTTON, CRect(0,0,19,14), this, _APS_NEXT_CONTROL_VALUE);
Because m_pBtn is not associated with a resource editor created control, it's createed from scratch and subclassed dynamically.
/T

This true only for first item, then you must increase value youreself:
m_pBtn->Create(_T("Button1"), WS_CHILD | WS_VISIBLE | BS_PUSHBUTTON, CRect(0,0,19,14), this, _APS_NEXT_CONTROL_VALUE+1);
m_pBtn->Create(_T("Button2"), WS_CHILD | WS_VISIBLE | BS_PUSHBUTTON, CRect(0,0,19,14), this, _APS_NEXT_CONTROL_VALUE+2);
You keeping unique values. You need do this only in one scope, so when you
create item with different's parent you can use same ID's:
m_pBtn->Create(_T("Button1"), WS_CHILD | WS_VISIBLE | BS_PUSHBUTTON, CRect(0,0,19,14), pWnd1, _APS_NEXT_CONTROL_VALUE);
m_pBtn->Create(_T("Button2"), WS_CHILD | WS_VISIBLE | BS_PUSHBUTTON, CRect(0,0,19,14), pWnd2, _APS_NEXT_CONTROL_VALUE);
There is no problem, couse different parent's: pWnd1, pWnd2.

Hi again,
What must I include in order to use the _APS_NEXT_CON... value?
|
|
|
|

I'm sort of a newbie when it come to Visual C++... and I'm having trouble on this project that requires me to convert a file type from a software my previous groupmates have developed into an AVI format.
What should I keep in mind when it comes to making a program/function/module that converts a file from one type to AVI?
|
|
|
|
|
What's the type ? Is it freeware ? We created a screen grabber that grabbed AVI in an afternoon once, using a MS sample. I can't remember the details, but you could look in MSDN. Also, if it's freeware, Virtua Dub is at Source Forge, and it's freeware ( but GPL, so no good if your code is commercial )

When I use unicode in my CRichEditView based class I can input Unicode characters only from keyboard, and when I try input its by function SetWindowText every character, which takes code after FF, printing as two different character, how I can correct this.

Hi
I have asked this before and i got som answers, Thanks
I will send a stored procedures to the Sql server with ADO, the stored procedure will have som parameters like this:
_bstr_t bstrCreate ( L"Create proc AdoTestA "
L"as "
L"Declare @pkMbtID varchar(50),"
L"@MbtType varchar(50)"
L"INSERT INTO MBT (pkMbtID, MbtType) Values (@pkMbtID, @MbtType)"
L"return");
It seems unnecessary to send the parameters with create parameter or refresh after sending the stored procedure.
Is there a way that i can invoke the parameters direct into the stored procedure abow.
Or isn't that possible?

Hi,
I need help to load a third party DLL in my program. This DLL is not registring through regsvr32.
|
|
|
|
|
For starters, look up LoadLibarary() and GetProcAddress(). If you're trying to use COM objects that are in the DLL, but aren't being registered properly, then you'll need to contact the author of the DLL.

Arthur: I don't know. Why, do you think it's the sort of thing you're likely to say?
|

Can you explain me a little about LoadLibrary. coz I don't know any functions in that DLL
|
|
|
|
|
LoadLibrary, just load's the dll, so you can call functions in it.
You need to have a function prototype to call a function in a dll.
Lets make a function that will register a com-dll (just like regsvr32.exe does):
typedef void (*f)(void);
BOOL MyFuncCallsADLL(TCHAR* szDll)
{
f pf; // our function pointer
HINSTANCE hDll = LoadLibrary(szDll);
if(hDll == NULL)
return FALSE; // we couldnt load library
//get function address
pf = (f)GetProcAddress(hDll, _T("DllRegisterServer"));
if(pf == NULL)
{
FreeLibrary(hDll);
return FALSE; //we couldn locate the function
}
//lets call that method
pf();
FreeLibrary(hDll);
return TRUE;
}

I recently installed MDAC 2.6 and since have been unable to set up connections to either Access or FoxPro databases. I did install the Jet drivers afterward since they are not included in the MDAC installation. Does anyone know of a way to 'roll back' an MDAC installation.
MS has a program called ComCheck which is supposed to do this. It is supposed to have an option to "Reconfigure MDAC" on the file menu. Funny it isn't there!
Thanks,
ed

Hi there !
I have a somewhat large project, which consists out of 5 DLLs and an EXE.
Everything is compiled with MULTITHREADED DLL RTL, and exactly the same settings.. I am using Visual C 6.0 SP5 ( and V C 7.0 BETA 2 which exhibits the same behaviour )
Now I do the following: BATCH BUILD-> Build all Debug COnfigs:
Engine.dll / Debug
Support.dll / Debug
ModuleG.dll / Debug
ModuleS.dll / Debug
Game.exe / Debug
The 5th DLL is a 3rd party one which is also in debug mode ( mswin-ruby16.dll ( RUBY Scripting language )
Ok now I start my program, but it does not work ( It seems to have some errors in the scripting language interpreters.... it just doesnt execute script code ...)
NOW i do exactly the same thing again
Batch Build / all Debug configs etc ....
AND NOW THE THING WORKS !!! Perfectly smoothly ....
I am out of clues, basically every second build of my game works fine, the others not.. There is not a single change in build configuration I checked and double checked for that, the source code stays the same to the last point !!!! ( There are also no dynamic changes to the code, like vc macros (post build,pre link etc)
So no changes at all... Every sceond build works... but sometimes it's only the third one....
..
Any idea what that could be ? Since VC7.0 has the same behaviour i think it has to be something that I am doing...
|
|
|
|
|
PS:
Code AND Build config stay the same...
And it does not matter if i do Batch Build REBUILD ALL (the marked debug configs) or just a normal BUILD...
Thanks

Here's a 'hey that sounds like...' response which may or may not be of any use.
On my 98 machine, which has run afoul of an attempt to roll back an IE5 install, Internet Explorer will not start the first time. I 'end task' with TM, then start it again, and it works. Been like that for months. The odd numbered attempts most often fail.
There are some other oddities with this machine (er, as you might expect with yours truly bonken its koppens) but I'm thinking your situation might be related - maybe some automation problem.
Have you tried this on a second machine?

When I press say a button, the program executes this piece of code
ShellExecute(this->m_hWnd,"open","site.html",NULL,NULL,SW_MAXIMIZE); to open a html page named "site.html". Ok it opens! I push another button that uses the code ShellExecute(this->m_hWnd, "open","site2.html",NULL,NULL, SW_MAXIMIZE); to open "site2.html". I would expect to open another window to display the second page, but NO, it uses the same window, and so i lose the info on "site.html". So how can I open TWO windows instead of one?
Hoping this is not a stupid question or an unsolvable one!
REGARDS!

|
|
ShellExecute(m_hWnd, "open", "iexplore.exe", "site.html", NULL, SW_MAXIMIZE);
could be one option. I will look for better solutions.
